Global Product Catalog Update

The Challenge: Updating a large volume of product data sheets for Heskins LLC. The task involved changing Copyrights, Emails, and converting SKUs specifically for US, Canadian, and Mexican markets without altering other technical data.

⚡ My Solution:

  • Region-Specific Logic: Updated SKUs to US versions for US files, and Canadian/Mexican versions for French files.

  • Brand Compliance: Replaced “Heskins Ltd” with “Heskins LLC” across all footers.

  • Precision Editing: Only touched specific sections (SKUs, Contact info) while keeping the rest of the content intact.

✅ Final Outcome: Accurate, market-ready product documentation ready for North American distribution.

⚡ My Solution:

  • Manual Formatting: Retyped and adjusted complex sections where software failed.

  • Layout Preservation: Ensured headers, footers, and paragraph styles matched the original exactly.

  • Optimization: Created a lightweight Word file that was easy to edit further.

✅ Final Outcome: A perfect digital twin of the original document in editable Word format, delivered within the deadline.

  • Data Aggregation: Extracted specific star ratings, review counts, and testimonial text.

  • Mapping: Organized all social proof data back to the original firm URLs for easy comparison.

  • Data Enrichment: Extracted estimated revenue, websites, and founding years.

Academic Data Extraction & Formatting

The Challenge: The client needed to extract structured data from complex academic PDF syllabi into a clean spreadsheet.

Goal: Capture specific details like course names, reading lists, authors, and page counts—data that automated tools often miss or mess up.

Academic PDF Research & Data Extraction Project

⚡ My Solution:

  • Manual Precision: Manually extracted course details and university names to ensure 100% accuracy.

  • Data Structuring: Organized reading lists with author names and online source URLs into a strict format.

Automated Data Consolidation & Deduplication

The Challenge: A client provided 4 separate spreadsheets containing over 4,000+ mixed customer records. The data was heavily duplicated, with inconsistent names (e.g., “Raj S.” vs “Raj Sahu”) and unformatted phone numbers.

Goal: Create a single, 100% clean Master Sheet for CRM import within 48 hours.

⚡ My Automated Solution: Instead of manual sorting, I engineered a custom Excel workflow:

  • Smart Merging: Consolidated all 4 sources into one raw database.

  • Advanced Logic: Applied formulas to identify duplicates based on “Name + Mobile Number” while preserving unique Email IDs.

  • Standardization: Auto-formatted all phone numbers to include country codes (+91) and fixed name casing.

  • Error Trapping: Used conditional formatting to highlight potential conflicts for a final manual check.

✅ Final Outcome: Delivered a 100% unique, CRM-ready master sheet well within the urgent 2-day deadline, saving the client roughly 20+ hours of manual work.
